PAGE 27. For further information on the uses of the bile 

 we must refer the reader to the recent work of Platner, ' Ueber 

 die Natur und den Nutzen der Galle/ Heidelberg, 1845. A 

 summary of his views on this subject is given in Miiller's Archiy, 

 No. 4, 1845. 



PAGE 29. Gastric juice. Dr. R. D. Thompson has published 

 an account of a series of experiments made with the view to 

 determine the acid or acids occurring in the gastric juice. In 

 order to prevent complication of the phenomena, the animals 

 were fed on vegetable food alone. His experiments tend to 

 show that no free hydrochloric acid is present in the stomach 

 of animals living 011 vegetable food, but that the free acid is 

 the lactic. A little acetic acid was also generally present. A 

 full account of his experiments may be seen in the ' London 

 Medical Gazette/ Oct. 1845, or in the ' Half-yearly Abstract 

 of the Medical Sciences/ vol. ii, pp. 347-51.
